The client grew up in the Patrick Gwynne house in whose garden this new house is built. It is organised around a grand piano, with a place for everything, and everything in its place; it is beautifully and rigorously detailed. The roof flips up in a sweet curving form which echoes the shape of the instrument beneath and giving views of the sky above. There are a number of references to the Gwynne house, such as the insets in the walls for displaying objects. Others include the line of the eaves and the use of coloured mosaic panels outside. But this is by no means pastiche and the buildings nestle very comfortably together in their beautiful shared garden, albeit with different external treatments.
